Air, water and soil pollution influence vegetation. Primary air pollutants such as reactive compounds of sulphur (sulphur oxides), nitrogen (nitrogen oxides), carbon monoxide and hydrocarbons, are emitted from fossil fuel combustion. Secondary pollutatnts, primarily ground level zone have severe implications on plants. These pollutants enter through stomata and adversely affect plant functions. Plant response to pollutants varies with species, age, variety and other abiotic factors. Sulphur dioxide increases stomatal opening resulting in loss of water, disrupts photosynthetic mechanism, causes interveinal cholorosis, and reduces quanity and quality of plant yield. Ozone, among all the pollutats, has been documented to have the most detrimental effects on the plants.
